As someone who learned Ada for a defense job years ago, I’ve been wondering how long it was going to take until I saw others comparing Rust to it, both in the sense of the language “safety” goals and the USG pushing for it.
While the rust compiler is leagues better than any Ada compiler I ever had the misfortune of dealing with, the day to day pain that Rust incurs will probably always be a thorn in it’s side
I was taught this too growing up in rural america. Did it myself at some land my grandparents had.
Best explanation I’ve heard for why it “works” is that when looking for places to first install pipes the location tends to be obvious or intuitive, so then years later when someone needs to find it again we naturally trend to the same rough area, pull out those stupid rod things and when they randomly cross there’s a pipe there cause we’re already standing in the general right spot. Get a high enough success rate and our brains start to think there is causation to the correlation.
For me, I view Apollo as the highschool quarterback winning the homecoming game.
In the context, its a great achievement. A lot of time, effort, and luck all came together at just the right moment to create an entertaining spectacle. The school is all happy and celebrating, students will remember that moment for years to come. But in the grand scheme of things, it’s not that big of an achievement since everyone there will move on to bigger and greater things, except they won’t have a student body cheering them on.
I think saying the Apollo program is one of the greatest achievements of mankind falsely puts it on a pedestal and forever sets up all other achievements as being lesser. Makes us all feel like anything that isn’t chasing that glory isn’t worth it. It’s an achievement for sure, but not the biggest. If I had to give the greatest achievement in space technology to anything, I’d give it to either GPS or GOES.
Short answer: it’s not that we don’t have the technology, its that we don’t have a reason to. With very few exceptions, if you can do it on the moon you can do it on earth or in Earth orbit
Long answer: in the space industry/field the moon is incredibly boring, relatively expensive to get to, and adds an extra step of logistics to an already complicated mission profile. Most space related technology advancement efforts have gone into doing things in orbit and there is more to do there than on the moon, it’s logistically simpler, and cost is orders of magnitude less. Stuff is still advancing there, think Hubble vs James Web, GPS 1 vs GPS 3, the entire GOES system. In terms of technical challenges, they’re far more interesting than anything on the moon, but it’s not as flashy/headline grabbing so it’s not talked about much.
The US going to the moon in the 60/70s was a rare combination of a win for scientists, politicians, and the people. The political incentive went away since as the USSR space program collapsed so too did political pressure to continue to put men on the moon and “prove 'Murica is better than those damn commies”.
In modern times the political incentive is returning with the continued efforts by China to do more stuff in space so we get the Artemis program, but the incentives aren’t that strong which is why the program has moved so slowly.
To me 16 is long haha.
I usually end up running with 16 characters since a lot of services reject longer than 20 and as a programmer I just like it when things are a power of two. Back in the Dark Times of remembering passwords my longest was 13 characters so when I started using a password manager setting them that long felt wild to me.
I do have my bank accounts under a 64 character password purely because monkey brain like seeing big security rating in keepass. Entropy go brrrrrrrrrrrr
I’ve used cloud based services for password managers for work and “self host” my personal stuff. I barely consider it self hosting since I use Keepass and on every machine it’s configured to keep a local cached copy of the database but primarily to pull from the database file on my in-home NAS.
Two issues I’ve had:
Logging into an account on a device currently not on my home network is brutal. I often resort to simply viewing the needed password and painstakingly type it in (and I run with loooooong passwords)
If I add or change a password on a desktop and don’t sync my phone before I leave, I get locked out of accounts. Two years rocking this setup it’s happened three times, twice I just said meh I don’t really need to do this now, a third time I went through account recovery and set a new password from my phone.
Minor complaint:
Sometimes Keepass2Android gets stuck trying to open the remote database and I have to let it sit and timeout (5 minutes!!!) which gets really annoying but happens very infrequently which is why I say just minor complaint
All in all, I find the inconvenience of doing the personal setup so low that to me even a $10 annual subscription is not worth it
Jesus dude, what brand TV do you have?
My LG issues a few hundred blocked requests throughout the day with heavy usage. I’ve never seen it wake up and phone home (my Nintendo Switch does it every hour for some stupid reason)
For graphics, the problem to be solved is that the N64 compiled code is expecting that if it puts value X at memory address Y it will draw a particular pixel in a particular way.
Emulators solve this problem by having a virtual CPU execute the game code (kinda difficult), and then emulator code reads the virtual memory space the game code is interacting with (easy), interprets those values (stupid crazy hard), and replicates the graphical effects using custom code/modern graphics API (kinda difficult).
This program is decompiling the N64 code (easy), searches for known function calls that interact with the N64 GPU (easy), swaps them with known valid modern graphics API calls (easy), then compiles for local machine (easy). Knowing what function signatures to look for and what to replace them with in the general case is basically downright impossible, but because a lot of N64 games used common code, if you go through the laborious process for one game, you get a bunch extra for free or way less effort.
As one of my favorite engineering phrases goes: the devil is in the details
Ada
It has a lot of really nice features for creating data types and has amazing static analysis during compile time.
But all the tooling around it is absolute crap making using the language unbearable and truly awful. If it had better tooling I could see that it would have taken a decent chunk of development away from C and C++
The ham radio thing makes me so sad, it really does seem like a dying hobby. But when I took my test the club sponsoring it had guys there who immediately berated me for using a practice test guide and getting a cheap piece of crap radio. Like yeah, I know it’s a terrible radio, but it was $70 with the practice guide and I’m a poor af college student. That little radio lasted me years and I only bought a new one cause it’s battery died and I couldn’t find a replacement
As someone who is in the aerospace industry and has dealt with safety critical code with NASA oversight, it’s a little disingenuous to pin NASA’s coding standards entirely on attempting to make things memory safe. It’s part of it, yeah, but it’s a very small part. There are a ton of other things that NASA is trying to protect for.
Plus, Rust doesn’t solve the underlying problem that NASA is looking to prevent in banning the C++ standard library. Part of it is DO-178 compliance (or lack thereof) the other part is that dynamic memory has the potential to cause all sorts of problems on resource constrained embedded systems. Statically analyzing dynamic memory usage is virtually impossible, testing for it gets cost prohibitive real quick, it’s just easier to blanket statement ban the STL.
Also, writing memory safe code honestly isn’t that hard. It just requires a different approach to problem solving, that just like any other design pattern, once you learn and get used to it, is easy.
I’m genuinely curious how saying that Linux GUI desktop has issues equates to gargling Microsoft’s balls?
So many people forget that while they understand how to use a Linux terminal and how Linux on a high level works, not everyone does. Plus, learning all of that takes time, effort, and tenacity, which not everyone is willing to do. Linus’s whole conclusion was that as long as that learning curve exists and as long as it’s that easy to shoot yourself in the foot, Linux desktop just isn’t viable for a lot of people.
But Linus has done a lot of public fuck ups therefore everything he says must be inherently wrong.
I think part of the “what do I do with this” factor for the iPad was that Apple (and other companies still to this day) were so hell bent on making everything smaller and more compact that releasing a larger product was marketing whiplash. Not to mention that smartphones were being pitched as this “do everything device” so why would you need anything else?
After you get over that marketing sugarcoating, it becomes pretty obvious what you’d use an iPad for. Internet and media consumption at a larger scale than your phone, easier on your eyes than a phone, but retains at least some of the lightweight smaller form factor that separates it from a regular laptop. Sure you didn’t have the stick it in your pocket advantage of a phone or the full keyboard and computational power of a laptop, but there was this in-between that for a modest fee, you could have the conveniences if you can live with/ignore the sacrifices.
I don’t think the MacBook Airs launch is a good comparison.
Sure there was an early adopter tax on being one of the first “thin and light” laptops, but people already know what you can use a MacBook for, there was already a large value proposition in having a MacBook, the extra cost was entirely being more portable than it’s full size counterparts. Everything you can do on a Mac, just way easier to take on the go.
I’ve read a few reviews on it, watched MKBHD’s initial review, and outside of a few demo apps they point to the vision pro having no real point to it. Which if true, then it falls in line with existing VR headsets that are a fraction of it’s cost and in a niche market, being three times the cost of your competitors is not a good position to be
It’s IEEE misinterpreting the guys original paper.
https://liuyang12.github.io/proj/privacy_dual_imaging/ (can’t find the full paper, but here’s the abstract at least)
The paper author straight up says the light sensor is impractical to use as an attack vector, but when you use it in conjunction with other sensors you might be able to gleam more information than most might think. It leaves me with question of what other sensors can you combine to start getting behavioral information that is a security threat?
I’ll say it worked for me. I read the IEEE headline, called bullshit, dug into it and yeah you can only get a tiny bit of information that you have to stretch pretty far to get useful conclusions from… But it’s more than the zero I initially thought. So props to the paper author, he met his goal. IEEE wanted sensationalized clicks, which they too unfortunately got.
Yup your right, I was wrong. Valve keeps the copyright regardless.
Dolphin situation was different though. https://dolphin-emu.org/blog/2023/07/20/what-happened-to-dolphin-on-steam/
Valve only ever insisted that Nintendo had to give Dolphin permission to distribute since Valve was afraid of a potential DMCA coming from Nintendo if Nintendo thought that the encryption keys were IP illegally being redistributed. Since Nintendo says emulators are illegal everywhere but a courtroom, Dolphin team knew that they’d never get an ok. Valve probably knew that but didn’t care enough to help fight that legal battle.
I’m not sure Valve cares about brownie points with Nintendo. The Steam Deck is a direct competitor against the Switch, Valve has done nothing to curtail the use of Switch emulators on Deck, and the work Valve has been doing makes using a switch emulator a better experience.
This whole thing only makes sense if Valve wanted to protect their IP. Involving Nintendo really does sound like blame shifting without having to actually go to court
I’m with you on the first part. It makes no sense for Valve to do this. Using LibUltra or not, Nintendo has been relatively lax on people creating new code for the N64. At least to my recollection only in cases where Nintendo felt their IP was directly being threatened did they try and take down fan projects. Even then they heavily rely on the redistribution of Nintendo IP to take things down. Admittedly I have only seen others talking about the Portal 64 project using LibUltra but even so that’s Nintendo’s fight, not Valve’s.
I don’t see how Valve could possibly be afraid of getting sued here by Nintendo, it doesn’t make sense. Valve did not create it, nor distribute, advertise, or aid in any way. IANAL but I don’t see how Valve could possibly be listed as a party to the lawsuit unless Nintendo lawyers agreed with Valve lawyers to go after this guy for IP theft.
TBH I see this more as Valve seeing that with a project this publicly known, if they don’t defend their IP here they’ll lose any future copyright claims and want to prevent it. They also see an opportunity here, blame Nintendo who won’t flinch it at since they get labelled legal bad guys all the time, no real dent to their reputation while saving Valve’s internet golden child perception. Valve would never do something like this so it MUST be Nintendo’s fault. Based on the comments in this thread and I’ve seen else where, that seems like a good assumption. Nintendo takes the heat while Valve protects their IP.
I had a boss who would send audio messages constantly. I’d be having a conversation with him, he’d get a text message on his phone, stop talking to me to mess with this phone, do a voice recording, mess it up cause he’d whisper it so others wouldn’t hear him (we still totally could), repeat it, rinse and repeat until he got it right, send it, then would ask me what we were talking about.
I’m convinced people who use voice messages have no situational awareness and are potentially psychopaths
